He l simplify the expression and combine like terms? 14t+5(1-4t)=?

distribute the parenthesis, that is multiply each term inside by the 5 outside

14t + 5 - 20t ( collect terms in t together )

5 + (14t - 20t ) =5 - 6t

The last option.

Step-by-step explanation:

1. By definition the ratio of the perimeter is the same as the scale factor.

2. Keeping this on mind, you can calculate the scale factor as shown below:

3. You can rewrite it as following:

4:3

4. Therefore, the ratio of the perimeter is 4:3
